There is already clonecd support (.ccd).
.img is supported but not listed in the supported image files. Just choose All files(*.*) and then the .img file which you want to mount, its working.
But .img is not a correct cd/dvd image file format, therefore it isn't listed in the supported images.
I think *.UIF or *.DAA may not be possible, but should be pretty nice to have them supported by Daemon Tools due to compressed ISO format... anyhow im aware that they aren't free formats (that's why i've said it may not be possible)...
What's the reason? Maybe to burn much more that 6 CDs (triple of more) to a single DVDs or just store them into your gigantic HDD to save space in the shelf... another good factor is the MD5 checksum inside them (at least in the *.UIF) to verify if they are good or damaged (ISO doesn't have that sadly).
Use RAR, ZIP, 7z, GZip as alternative? well, that formats aren't designed for mouting... and may require full decompression to HDD.
